"About the poster" at the end of each post

Hello, I would like to know if there's a way of removing the "about the poster" area at the end of each post that I make on my site.

Review: 2013 Mazda 3 GT
The part that I'm talking about (to make it more clear) is the very end of this post (any many others) that have "About MGReviews". Is there any way of removing that and not having it show in any post?
